TRAFFIC INDICATOR.

Application led December 3, 1922. Serial No. 605,723.

To all whom t may concer-n.' and are arranged in spaced relationk todefine Be it known that l, DE WITT H. WYATT, a a plurality of chambers7, the sides of said citizen of the United States, residing A-at websconstituting reflecting surfaces, and Columbus, in the county ofFranklin and also in connection with the crown protective State of Ohio,have invented certain new means for the lens 8. This lens is of the 60and useful Improvements in Traflic Indiconcavo-conveX type and `ispreferably cators, of which the following is a speciiiformed from redglass, the periphery of said cation. lens `being engaged with thebeveled facev The present invention is directed `to im- 9 of a leadgasket 10, said gasket being of o proveniente in traf'dc indicators, andparticusuch diameter as to fit snugly within the 65 larly to that typeadapted to be: located at opening 4. the intersection of streets todirect vehicu- A transversely curved band 11 is provided lar trafhc atsuch points. and is adapted to overlap the gasket 10 and The inventionhas for its primary object periphery of the lens, as clearly shown in toprovide an indicator of this character Figure 3. It will be noted thatthe inner 70 adapted to be anchored at the proper point, ends of thewebs 6 overhang the opening 4, the same being so constructed as to beand consequently the band 1-1 will bear illuminated so as to beeffectively employed thereagainst, thus holding the band tightly day ornight. in engagement with the associated parts.

A still further object of the invention is A disk 14 is provided, saiddisk being anto provide an indicator of this nature concliored to thesurface of the street by a screw structed in such manner that thelighting bolt 15, or in any other suitable manner. element andassociated parts will be located This disk is of a diameter slightlyless than 85 above the street level to prevent water colthe majordiameter of the dome, and conselecting therein. quently the peripherythereof is spaced from With these and other objects in view, as theinner wall of the base 2 of said dome. will appear as the descriptionproceeds, the This permits a slight relative movement beinventionconsists in the novel features of tween the disk and dome so that should90 construction, combinations of elements and the dome be subjected tojars incident to arrangements of parts, and hereinafter to the contactof a vehicle wheel therewith, the be fully described and pointed outinthe shock will be to some extent absorbed beappended claims. forebeing imparted to the disk. In the accompanying drawing: The disk 14 isprovided with a central Figure lis a fragmentary plan vie-w of theconical seat 16, and in which is loosely redevice, movably mounted theconical lower end of Figure 2 is a transverse sectional view, theannular reflector 17, said reflector hav- Figure 3 is an enlarged detailsectional ing a vertical flange 18 adapted to rest on view showing themanner in which thelens is the disk 14 shown in Figure 2.

The dome is formed witha fiat top move relative to the disk to relieve street 105 3 in which isformed a circular opening 4, vibrations imparted to the disk, thusproand immediately above the opening and longing the life of theincandescent bulbs 19, spaced therefrom is a crown 5. Formed insaidbulbs being mounted in sockets 20 cartegral with the crown and top arevertical ried by the reflector 17. webs 6, said webs being disposedradially The lens 8 is applied to the dome from 110 CII the interiorthereof, and consequently is limited in its upward movement by the crown5. After the lens 8 has been properly positioned relative the openingret the lead gasket 10 is forced in the opening under considerablepressure so that the Abeveled face thereof is impinged tightly againstthe periphery of the lens, thereby producing a water tight joint. Inthis vmanner moisture f, falling upon the dome will be prevented fromentering .the interior thereof, which would cause trouble with thecircuit for the bulbs, and corrosion of the reflector.

It will be observed that the webs 6 form- .Y ing the sides of thechambers 7 are divergingly arranged and that the rays of light projectedfrom r`the lens will fall thereon and be reflected thereby so as to bediscernible at various angles Iby drivers of approaching cars.

Current is furnished to the bulbs through the wires 20, said wires beingled through a pipe 21 from a source of supply.

What is .claimed is:

1. A traflic indicator 4comprising a dome,

a disk' anchored to the roadway and confined within the dome to limitthe lateral movement of said dome, a crown, a reflector carried by thedisk, an illuminating medium carried 'by the reflector, a lens fixed inthe top of the dome below the crown, radial webs connecting the crownand top of the dome to produce independent chambers into which the lightrays from the lens are projected.

2. A traffic indicator comprising a dome, the base of said dome beingadapted to rest upon the surface of a roadway, a disk anchored on thesurface of the roadway and having its inner periphery normally spacedfrom the base of the dome and .adapted to contact. with the periphery ofsaid dome to limit the horizontal movement of the dome with respect tothe disk.

In testimony whereof I afiix my signature.

DE WITT H. WYATT.
